Which of the following conclusions is from industrial melanism?
Camouflage causes the white moths to get caught by predators more even in rural areas during industrialisation.
During industrialisation, white variant of moths got wiped out completely in urban areas.
During industrialisation, lichen will increase in number.
In a mixed population, those that can better adapt, survive and increase in population size.
Which of the following is not the example of evolution by anthropogenic actions?
Herbicide resistant varieties
Antibiotic resistant microbes
Darwin Finches
Different breeds of dogs
Adaptive radiation does not follow which of the following statements?
Black bird on Galapagos islands observed by Darwin as an amazing example of Adaptive Radiation.
All the varieties of Finches evolved on the same island, from the original seed-eating features to insectivorous and vegetarian finches.
Australian marsupials, which are similar to each other evolved from an ancestral stock but all within the Australian island continent.
More than one adaptive radiation appeared to have occurred in an isolated geographical area representing different habitats, Known as convergent evolution
Which of the following is not Australian marsupial?
Spotted cuscus
Bobcat
Sugar glider
Koala
Which of the following is placental mammal?
Bandicoot
Numbat
Wombat
Which of the following placental mammals appears to be similar to a corresponding marsupial NUMBAT?
Anteater
Mole
Wolf
Evolution is not
a stochastic process
Based on chance events in nature
Based on chance mutation in the organisms
Directed process in the sense of determinsm
Which of the following statements is not true if we consider postulates of Darwinian theory of evolution?
Evolution by natural selection would have started when cellular forms of life with similarities in metabolic capabilities originated on Earth
The rate of appearance of new forms is linked to the life cycle or the life span.
Fitness is based on characteristics which are inherited.
Adaptive ability is inherited.
Fitness is not
Something for which nature selects
End result of the ability to adapt and get selected by nature
Based on characteristics which are inherited
Considered when cellular forms of life were originated.
Darwinian theory of evolution-
Branching descent and natural selection are two auxillary concepts of this theory.
Natural selection is based on some factual observations.
Was influenced by work of Alfred Wallace on populations.
Both A and C
In the story of this world, evolution is a …... and in the story of life on Earth, evolution is……
Process, result of environmental changes
Result of environmental changes, process
Process, result of natural selection
Result of natural selection, process
Which of the following was the novel insight of Darwin in his theory?
Variations are heritable and make resource utilisation better for few will enable only those to reproduce and leave more progeny
Population size will grow exponentially if everybody reproduced maximally.
Natural resources are limited yet populations are stable in size except for seasonal fluctuations.
Members of populations vary in characteristics.
Two peaks will be observed in which of the operation of natural selection?
Disruptive
Directional
Stabilising
Peak getting higher and narrower is observed in which of the operation of natural selection?

If a population has dominant phenotype in 1600 individuals out of 2000 then calculate the frequency of heterozygote.

Around 23%
Around 46%
26%
25%
If more individuals acquire peripheral character value at both the ends of the distribution curve; in such case natural selection has resulted in
Stabilization
Disruption
May be B or C depending upon population parameters
